    Subject[PATCH 5.17 105/158] net/mlx5e: Block rx-gro-hw feature in switchdev mode
    Date
    From: Aya Levin <ayal@nvidia.com>

    [ Upstream commit 15a5078cab30d7aa02ad14bfadebf247d95fc239 ]

    When the driver is in switchdev mode and rx-gro-hw is set, the RQ needs
    special CQE handling. Till then, block setting of rx-gro-hw feature in
    switchdev mode, to avoid failure while setting the feature due to
    failure while opening the RQ.

    Fixes: f97d5c2a453e ("net/mlx5e: Add handle SHAMPO cqe support")
